After upgrading from 455.45.01 to 460.32.03, I get a black screen after loading of nvidia-modeset: First, the screen goes black, then the backlight is toggled several times (about 10 times), finally it stays blank and dark. Kernel log contains: Jan 10 19:05:05 localhost kernel: [ 5.773942] [drm…

Thanks for the tips! However: enabling CSM in bios (but still boot using efi) That would also mean to disable secure boot, in turn causing other issues (security, functionality loss in Windows). I can for sure try that for a test, but could you explain / link to some explanation on why you expe…

The error you’re getting is a recurring bug on older hardware, seems to be related to early vbios init. Turning on CSM often worked around it. Since this bug is very harware specific, it’s rarely ever getting fixed.

Thanks, I will give CSM a try later then (disabling SecureBoot means unregistering my signing keys, so I am reluctant there). For me, the issue is new with the 460 drivers and to my memory never showed up before even though I have been following new releases (also beta) for years, so in my case, it…

I am seeing a similar error, machine boots ok but after suspend/resume shows a black screen then after ~120 seconds an error message. This is with nvidia-460 on a Razr Blade 15" (2018) with external monitors. Enabling CSM did not help. [also nvidia-drm.modeset=1 does not help]. Are you sure this is…

[image] olifre: Thanks, I will give CSM a try later then (disabling SecureBoot means unregistering my signing keys, so I am reluctant there). Actually, turns out I can’t: Activating CSM on that laptop happens implicitly only after the following steps: Disable SecureBoot (which leads to loss…

Same problem here when I close and then open the laptop lid, anybody knows if is there a fix now?

I have the same issue on my machine. I also notice the same error in my log files: kernel: nvidia-modeset: ERROR: GPU:0: Display engine push buffer channel allocation failed: 0x65 (Call timed out [NV_ERR_TIMEOUT]) kernel: nvidia-modeset: ERROR: GPU:0: Failed to allocate display engine core DMA pu…

I’ve run in the same issue, see my duplicate help request (I’m sorry about making a duplicate). Today I’ve tried various bioses for my HP zbook studio G3 (Nvidia Quadro M1000M) but it didn’t help. I played around with secure boot and legacy bios modus. Nothing worked. Added to the issue of crashing…

Note that this still happens for me with 460.56 (but there was also no related change in the release notes). If a new bug report might be helpful for further investigation, just let me know.
